: Many portable units are dual-voltage , allowing them to switch between standard 120V household outlets and 240V industrial supplies.
: Higher amperage allows for thicker and faster cuts. For light work (up to 12mm), 30A is often sufficient; for professional workshop tasks (up to 25mm), a 40-50A machine is the standard. buy plasma cutter
: Pilot arc technology is highly recommended because it starts without touching the metal, making it ideal for cutting through rust, paint, or expanded metal. Top Product Recommendations for 2026 : Many portable units are dual-voltage , allowing
Buying a plasma cutter requires matching the machine’s power to your most frequent projects rather than just the thickest piece of metal you might ever cut. A high-quality unit should offer efficient cutting speeds, a manageable duty cycle, and affordable, long-lasting consumables. Key Specifications to Consider : Pilot arc technology is highly recommended because
: This measures how long a machine can cut continuously in a 10-minute window. A 60% duty cycle means six minutes of cutting followed by four minutes of cooling.
